GENTOO LINUX SECURITY ANNOUNCEMENT 200301-12
- - --------------------------------------------------------------------
PACKAGE : cvs
SUMMARY : arbitrary code execution
DATE : 2003-01-21 09:43 UTC
EXPLOIT : remote
- - --------------------------------------------------------------------
- From advisory:
"By sending a malformed directory name it is possible to trigger an
error condition that will make the function return at a point where a
global pointer variable is already freed and has not got a new value
assigned yet. This will result in a classical double-free() when the
next Directory request is handled. With the help of other CVS requests
it is possible to either leak some information that could be used to
determine the heap position or to execute arbitrary code on systems
that are known to be vulnerable to this kind of bugs."

SOLUTION
It is recommended that all Gentoo Linux users who are running

emerge sync
emerge -u cvs
emerge clean
